Compass directions

are the compass directions (N S E W = nan er sar tel) in Verdurian only
nouns, or can they be adjectives or adverbs as well?

For example, how would one translate 10 cemisî south
of Pelym? I can imagine any of

Dec cemisî er Pelymei (though this sounds like
10 cemisîand of Pelym)

Dec cemisî ad/im erán Pelymei

Dec cemisî erece Pelymei

Dec cemisî er azh/dör Pelymán

And how about southern Viminia? Is that er
Vimínë, which sounds to me more like the south of
Viminia (which, admittedly, has a similar meaning)? Or maybe
erise/erete/erë Vimínia?

And is Viminia is west of Caizura translated as
Vimínia zet tróue im (soán) telán
Caizure? Or perhaps Vimínia zet tróue telece
Caizure or something like that?

How would one express North Elbonia or Lower Slobovia,
if that's a country name? For example, there's a difference between
west(ern) Germany and West Germany (the second no longer
exists, while the first just describes a region inside a country). Is
northern Elboniananise/nanete/nanë Elbonia
while North Elbonia would be Nan-Elbonia or
something like that? Or is no distinction made?

And would Lower Slobovia be Hip-Slobovia, by
analogy with upper which is translated as ir =
above in Eng2Ver? Or maybe Basë Slobovia? And
are their pals further into the mountains Ir-Slobovia or
Altë Slobovia?

How about He lives in the South? Zhesei im soán
erán, perhaps?

Finally, is there a traditional order in Verdurian for reciting the
compass directions? English and German both have North, South, East,
West and Norden, Süden, Osten, Westen, but Japanese, for
example, has 東西南北 tou-zai-nan-boku or
East, West, South, North.

And what about compass directions in between? English, German, and French
have northeast, Nordost(en), and nord-est (that
is, first north-south, then east-west), while Japanese has 東北
touhoku/higashikita or east-north (that is, with
the two components in the opposite order). Does Verdurian have
sarnan or nansar? Or maybe some other
compound of the two words such as sarise/sarete/sarë
naneastern north or sar naneieast
of north? And how is (something is located) northeast of ...
expressed?
